When Facebook recently announced its Android-related event, scheduled for April 4, speculation immediately mounted that the event would reveal a Facebook phone designed by HTC, based on previous rumors. According to a new report, however, that's not the case.

According to a new article by Wall Street Journal, Facebook is simply becoming more visible on Android, and that will reportedly begin with HTC. In a nutshell, the idea is to put Facebook on the Android home screen, increasing the time people spend on the network.

In turn, this will increase the network's advertising revenue. It's a clever idea, but supposedly only HTC has shown much interest, resulting in HTC phones supposedly being used at the April 4 event. This won't rule out other manufacturers getting on board with the initiative, but it puts HTC as the poster child for now.

HTC hasn't commented on its current relationship with the world's largest social network but it doesn't seem sour. The two companies have a history together, however, as they collaborated on the Salsa and ChaCha handsets that came with integrated Facebook buttons. HTC's proprietary Sense interface for Android also included quite a bit of Facebook functionality in the past.
